Procedure

To a mixture of 5-chloro-1-pyrimidin-2-yl-1H-pyrazole-4-carboxylic acid (50 mg, 0.22 mmol) in 1.0 mL of DMF is added sequentially DIEA (0.08 mL, 0.44 mmol), 1-adamantan-1-ylmethan-amine (36 mg, 0.22 mmol), and BOP (115 mg, 0.26 mmol). The resulting mixture is stirred at RT for 18 h. Water (3 mL) is added, and the mixture is extracted with EtOAc (5 mL). The EtOAc layer is dried (Na2SO4), filtered, and evaporated in vacuo to give a reddish/brown oil. Purification by silica gel column chromatography (gradient from 90% EtOAc/hexane to EtOAc) affords the title compound as a light reddish/brown solid. 1H NMR (400 MHz, CDCl3) δ 8.89 (2H, d, J 4.8), 8.28 (1H, s), 7.41 (1H, t, J 4.8), 6.47 (1H, bs), 3.18 (2H, d, J 6), 2.01 (3H, s), 1.69 (6H, m), 1.58 (6H, s). MS (M+1)=372.19; RT=1.31 min. *IC50.
